16. Geolocation
• Like GPS for the browser
• Browser gathers information about nearby
wireless access points and computer’s IP
address. Then it sends this information to the
default geolocation service provider, Google
Location Services, to get an estimate of
location. That location estimate is then shared
with the requesting website.

function(position){
position.coords.latitude,
position.coords.longitude
}
);
